Product details
Overview
TLV2765IPWR from Texas Instruments is a quad-channel, 1.8 V micropower rail-to-rail input/output operational amplifier with individual shutdown control per channel. It operates from 1.8 V to 3.6 V, draws only 20 μA per channel, delivers 500 kHz bandwidth and 0.20 V/μs slew rate, and supports industrial temperature range (−40°C to +85°C). It is used in ultra-low-power sensor signal conditioning and battery-powered instrumentation.
For engineers reviewing the TLV2765IPWR datasheet, TLV2765IPWR pinout, TLV2765IPWR application, or TLV2765IPWR equivalent, key selection criteria include its 10 nA per-channel shutdown current, rail-to-rail I/O at 1.8 V, 550 μV input offset voltage, 95 nV/√Hz input voltage noise, and TSSOP-16 package compatibility with space-constrained portable designs.
Technical Context
The TLV2765IPWR implements CMOS input-stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 10–75 mV of supply rails. Its micropower design integrates low-input-bias-current circuitry (3 pA typical) and ultralow shutdown logic that reduces supply current to 10 nA per channel when SHDN is low.
Each of the four amplifiers features independent shutdown pins (1/2SHDN on Pin 6, 3/4SHDN on Pin 15), allowing selective channel activation. The device maintains stable unity-gain operation with 10 pF load capacitance and exhibits 63° phase margin, supporting robust performance in precision DC-coupled and low-frequency AC signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from two AA/AAA cells (1.8 V end-of-life) or NiMH/NiCd (2.4 V nominal). |
| Supply Current per Channel | 20 μA - allows continuous operation for years on coin-cell batteries in always-on monitoring systems. |
| Shutdown Current per Channel | 10 nA - reduces total system quiescent power to nanoampere level during sleep modes. |
| Input Offset Voltage | 550 μV - ensures ≤0.5 mV error in 12-bit ADC front-ends with gain ≤10. |
| Unity-Gain Bandwidth | 500 kHz - supports accurate amplification of signals up to ~50 kHz with <0.1% gain error. |
| Input Voltage Noise | 95 nV/√Hz at 1 kHz - suitable for low-level thermistor or bridge sensor interfaces without significant SNR degradation. |
| Output Drive Capability | ±5 mA - drives 10 kΩ loads while maintaining rail-to-rail swing and linearity. |
Pinout & Package
TSSOP-16 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - rail-to-rail capable, sourced/sunk up to ±5 mA. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance CMOS node (3 pA bias current). |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts common-mode voltages from −0.2 V to VDD + 0.2 V. |
| 4 | GND | Analog ground reference - must be tied to low-impedance PCB ground plane. |
| 5 | 1SHDN | Shutdown control for Amplifier A - logic low (≤0.6 V) disables amplifier; high (≥2 V) enables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2764IPW | Same family, same pinout, but lacks individual shutdown per channel - uses single SHDN pin for all four amplifiers. | Suitable where global enable/disable suffices; not appropriate for partial-channel power gating. | Select TLV2764IPW if system-level power sequencing simplifies firmware and layout. |
| LP324DT | Quad op-amp with 45 μA/ch supply current, no shutdown, wider supply range (3 V to 36 V), higher offset (3 mV). | Targeted at industrial analog I/O modules requiring high-voltage tolerance, not ultra-low-power battery use. | Choose LP324DT only when operating above 3 V and shutdown functionality is unnecessary. |
Compared with TLV2764IPW, TLV2765IPWR enables finer-grained power control per amplifier; compared with LP324DT, it achieves 2.25× lower quiescent current and supports 1.8 V operation - essential for modern energy-harvesting and coin-cell designs.

FAQ
What is the maximum recommended supply voltage for TLV2765IPWR?
The absolute maximum supply voltage for TLV2765IPWR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric shift and accelerated aging; operation at 3.6 V is validated for full industrial temperature range (−40°C to +85°C) and specified output drive capability.
Does TLV2765IPWR support true rail-to-rail input at 1.8 V supply?
Yes, TLV2765IPWR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at 1.8 V supply. This allows direct interface with sensors whose output swings below ground or above VDD - such as bridge circuits with center-tap bias or piezoelectric elements - without external level-shifting circuitry.
How does the shutdown function behave on TLV2765IPWR pins 5, 10, and 14?
Pin 5 (1SHDN) controls Amplifier A only; Pin 10 (2SHDN) controls Amplifier B only; Pin 14 (3/4SHDN) controls both Amplifiers C and D together. All three inputs recognize VIH ≥ 2 V (at VDD = 2.7–3.6 V) and VIL ≤ 0.6 V as valid logic high/low, with turnon/turnoff times of 5 μs and 0.8 μs respectively under RL = 300 kΩ load.
Can TLV2765IPWR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - at VDD = 1.8 V and TA = 25°C, TLV2765IPWR delivers VOH ≥ 1.77 V (within 30 mV of VDD) and VOL ≤ 30 mV (within 30 mV of GND) into 10 kΩ. This meets rail-to-rail specification for both sourcing and sinking configurations, verified across full industrial temperature range.
Is TLV2765IPWR qualified for automotive applications?
No - TLV2765IPWR is rated for industrial temperature range (−40°C to +85°C) and carries no AEC-Q200 qualification. For automotive use, TI recommends the TLV2765-Q1 variant (not TLV2765IPWR), which undergoes additional stress testing and PPAP documentation per automotive quality standards.
